(X-3)+2(3X+1)=3(5X+2)
Soluções para a tarefa
Respondido por
1
(x - 3 ) + 2 (3 x + 1 ) = 3 (5 x + 2 )
(x - 3 ) + 6 x + 2 = 15 x + 6
x - 3 + 6 x + 2 = 15 x + 6
7 x - 1 = 15 x + 6
7 x - 15 x = 6 + 1
-8 x = 7
x = -7/8
(x - 3 ) + 6 x + 2 = 15 x + 6
x - 3 + 6 x + 2 = 15 x + 6
7 x - 1 = 15 x + 6
7 x - 15 x = 6 + 1
-8 x = 7
x = -7/8

(x - 3) + 2.(3x + 1) = 3.(5x + 2)
x - 3 + 6x + 2 = 15x + 6
7x - 1 = 15x + 6
- 1 - 6 = 15x - 7x
- 7 = 8x
8x = - 7
x = - 7/8
x - 3 + 6x + 2 = 15x + 6
7x - 1 = 15x + 6
- 1 - 6 = 15x - 7x
- 7 = 8x
8x = - 7
x = - 7/8
